I wouldn't bother. For what they want for those things you can get a decent used tractor, that is useful for firewood and numerous other practical chores, growing a whopper garden, running a PTO generator, a sprayer, log splitter whatnot. that is what is cool about a tractor, you are buying a multi tool powerhead with wheels that is self propelled and has a zillion attachments possible. Heck, I wish I had all the attachements for my baby wheelhorse for that matter. someday...
I live/work on a big farm that employs several farm families, plus guys who drive here to work every day. Some of them have atvs, etc..but everyone defaults to a real tractor to do work with. I see them more used for just joyriding to the mailbox more than anything else.
I have access to just all sorts of equipment..do my firewood with a tractor and a cargo box on the back. I built the thing so I could use the hayfork to just slip into it, pick it up a little, tip it forward, done, down the road..or trail.
I don't have a big winch, but just using chains I have skidded out big logs to an open area to cut them up. Used the same deal when pulling down snagged trees as well, chain them up at the butt and grannyiest gear pull them down and out. If the log is light enough, I can slip out of the box right then, go around, pick up the log with the forks in the middle and start sawing at my best most practical height off the ground. Can't beat it with two sticks.
You just can't do that stuff with an atv or utv.
As an alternative, what one of the other posters mentioned, get a used four wheel drive truck, make it not road legal then, as in don't bother insurance/tags all that stuff, just keep it off road, beef it up a little, cut the fenders off maybe, and put real ag style/tractor tires on it, maybe chains. A rig like this is called a "trucktor" any number of home brewed variations out there, some I have seen are really spiffy, too.
A decent used 4wd truck can be had for less than what they want for a little sport buggy. You won't be driving it all that far, so fuel costs won't be much of an issue, and wear and tear won't be that bad if you refrain from overloading it, and you'll always have a cab to ride in that is more or less weatherproof and has a real heater and stuff and a place to stash your tools behind the seat if you get a kingcab/crewcab. Parts are more available too. I mean, heckfire, they want as much for a new two cylinder motor for one of those things as a v-8 crate engine! What's up with that?
Just a thought. For what one of those atvs or utvs cost new (not counting the cheaper chicom ones out there now) you could get a good used truck and go nuts modifying it, have some fun and build a unique to you personal woods work machine. Just think "never to be used onroad again" and it REALLY opens up the modding potential. Bwa, if it was a diesel then you could use offroad farm diesel in it and not worry about getting caught...
with all that said, there is ONE sorta ATV thing I have wanted a long time, if I ever see one well used and ultra cheap I will get one. Saw a guy demoing one at a dealers before, shazzam, best little point A to B little machine I ever saw, any terrain, anywhere, anytime. Plus it has attachments and you can haul with it, a trailer, or skid smaller stuff or.. and do some real work, and it can be street legal as well! Check this thing out:

If I get one ever I will try to make it a single cylinder diesel, that's about all the mods necessary for it over "stock" I think. If they ever have a factory diesel option..that is one of the few things I would go in hock for and make monthly payments for.
